Evolutionary Genomics of Sister Species Differing in Effective Population Sizes and Recombination Rates

This study compares population-genomics data between two sister species, D. pulex and D. pulicaria, to understand genetic mechanisms of ecological speciation and identify genes under positive selection.

The Genome-wide Signature of Short-term Temporal Selection

This study analyzes genome-wide selection patterns in Daphnia pulex over nine years, finding fluctuating selection with near-zero mean coefficients and weak negative selection on minor alleles.

Global port survey quantifies commercial shippings effect on biodiversity

The paper quantifies how commercial shipping affects biodiversity by analyzing environmental DNA in ports across multiple regions, finding increased community similarity with more ship voyages and identifying non-indigenous species.

Chromosomal rearrangements preserve adaptive divergence in ecological speciation

The paper analyzes chromosomal rearrangements in Daphnia species to show their role in preserving adaptive divergence during ecological speciation.

Global invasion history of the world’s most abundant pest butterfly: a citizen science population genomics study

The paper uses citizen science to collect genetic data on the invasive butterfly Pieris rapae, revealing its global spread through human activities and four founding events over 160 years.

Patterns of divergence across the geographic and genomic landscape of a butterfly hybrid zone associated with a climatic gradient

The paper examines divergence patterns in a butterfly hybrid zone, identifying genomic regions under selection and their association with ecological and intrinsic factors.
